Specification of Letters Patent. Patented Mar, 24, 1914 Application filed August 1, 1912. Serial No. 712,661. 7

To all whom it may concern Be it known that I, WALTER D. BANES, a citizen of the United States, residing at Germantown, in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Grease-Cup Closure, of which the following is a specification.

grease cup closures.

The object of my invention is to provide an improved closure or lid for a receptacle, such for example, as a grease cup, and means for controlling the same.

The invention comprises an extremely simple, efficient and inexpensive means for securing the lid to the cup and at the same time permitting the movement of the lid from the closed to the open position and vice versa, and means for maintaining said lid in either of said positions as desired.

Referring to the drawings, which illustrate merely by way of example a satisfactory embodiment of my invention Figure 1 is an elevation of a grease cup with the lid closed. Fig. 2 is a plan view with the lid opened. Fig. 3 is a vertical section on line 33 of Fig. 1. Fig. 4. is a vertical section on line 4-4 of Fig. 2. Fig 5 is a'plan view of the lid with the associated mechanism removed. Fig. 6 is a perspective view of the spring.

Similar numerals refer to similar parts throughout the several views.

Referring to the drawings, 6 indicates the usual form of grease cup, 7 a lid there for. This lid is provided in its sides or vertical flange with the horizontal slot 8, the restricted opening 9 below said slot and the points or projections 10 at the lower edge of the flange and on each side of opening 9. The spring 11 is secured to the side of the grease cup by the rivet 12 or other suitable means. vertical extension from the rivet 12 to the bend 13, then a horizontal extension 14 and an inclined extension 15 terminating in a substantially horizontal ring portion 16.

Referring especially to Fig. 6, it will be noted that the part 17. of the vertical extension of spring 11 and a small portion 14 of the horizontal extension, adjacent the angle 13, arev wider than the balance of the horizontal extension adjacent thereto. slot 8 in the lid 7 is adapted'to receive My invention relates to improvements in This spring has an approximately The these'broader parts 14 and 17 while the open1ng9 is adapted to receive the narrower extension 15.

In assembling the parts together, the spring member 15 is first secured to the wall of the grease cup by the rivet 12 or other suitable means. By inserting a tool between the vertical extension of the spring and the wall of the grease cup, the upper part of the spring is deflected away from the wall of the grease cup sufliciently to bring the narrower extension 15 beyond the wall of the grease cup so that the opening 9 1n flange of lid 7, will receive said narrower extension 15 and permit the lid to be placed upon the grease cup, and upon releaslng the spring 11 the wider portion 14 will enter theslot 8 thus securing the lid 7 in position.

The pressure of the spring 11 against the flange of the lid, will hold the same normally closed. Upon lifting the lid however into the position shown in Fig. 4, the slot 8 passes around the angle 13 into the position embracing the vertical part 17 of the spring, until stopped by the shoulders 18.

The points 10 and 18 serve as bearings between the wall of the cup and the spring 11. In moving the lid from the position shown in Fig. 3 to the position shown in F1g.:4, the points 18 pass. from one side to the other of the points or center 10, and thus the pressure of spring 11 is exerted on the points or bearings 18 above the center 10 in Fig. 3, and normally holds the lid shut. In the position shown in Fig. 1, the pressure of'spring 11 is exerted upon the bearings 18 below the center 10 and normally holds, the lid open. This form of spring-controlled action is commonly described as an over'the-center action or'movement, in that the pressure of the spring passes from one side to the other side, or over the center of movement of the body upon which it is exerted. Thus the spring 11 serves as a hinge element in the slot 8, and also serves normally to maintain the lid in the closed or open position as desired, the elements being easy to assemble or disassemble simply by pressing the spring outwardly until the narrower portion thereof may pass through the narrower opening 9 of the lid flange.

What I claim is 1. A grease cup closure comprising a Su-bsta-ntially flat body with a flange at an angle therewith, the flange provided with a horizontally extending slot, and a spring secured to the cup having a straight substantially vertical extension with an. adjacent extension at an approximate right angle therewith, the spring adapted to seat in the slot and normally maintain the closure in open or closed position.

2. A closure for a receptacle comprising a lid with a substantially vertical flange having a horizontal slot therein, a flat spring secured to the vessel having a substantially vertical extension and a substantially horizontal extension adapted to engage in the slotted flange, said spring provided with shoulders for limiting the movement of the slotted flange thereon.

3. A receptacle and a closure therefor comprising a lid having a substantially vertical flange, said flange provided with a horizontal slot and a narrower opening communicating therewith, a spring member secured to the receptacle having an extension adapted to fit the horizontal slot and a narrower extension adapted to pass through the narrower opening communicating with the slot.

4:. A receptacle and a closure therefor comprising a lid having a substantially vertical flange, said flange provided with a horizontal slot and a narrower opening communicating therewith, a spring member secured to the receptacle having an extension adapted to fit the horizontal slot and a narrower extension adapted to pass through the narrower opening communicating with the slot, and a projection on the spring adapted to limit the relative movement between lid and spring.

5. A receptacle and a closure therefor, comprising a lid with a vertical flange, a recess in the flange, a spring secured to the receptacle having a vertical extension and a horizontal extension and adapted to engage in the recess of the flange so that the flange will pass from the horizontal portion of the spring to the vertical portion and vice versa, as and for the purpose specified.
